PHP和Oracle - oci_connect（）ORA-12705：无法访问NLS数据文件
We've been using Oracle on our server for years, but someone from IT removed it yesterday without clear warning and it's really thrown our systems!
I've acted on the advice from cwallenpoole (thank you!) and have made good progress, and PHP is now at least including the oracle functions (ie oci_connect) but I am now experiencing another error message:
"Warning: oci_connect() [function.oci-connect]: ORA-12705: Cannot access NLS data files or invalid environment"
We have ensured the tnsnames.ora etc files are in the correct place, but still having no joy :(
